When print data described in structured language is received from a transmitter, the print data is analyzed by an analysis unit and a determination is made as to whether or not there is unprintable data in the print data. A condition table stores print conditions for determining printability by a print unit, these print conditions being associated with print settings information that has been set with respect to the print data, and a condition determination unit controls printing by the print unit by referencing the condition table based on an analysis result of the analysis unit and the print settings information.
